Differences in the safety profile of tofacitinib in Japanese patients versus the global population, such as a higher risk of herpes zoster, have been reported. Objectives: We conducted post hoc analyses of tofacitinib treatment in Japanese patients with moderate-to-severe UC in two global phase III studies. Methods: In OCTAVE Induction 1 (NCT01465763), 62 patients were randomized to placebo or tofacitinib 10 mg twice daily (b.i.d.). In OCTAVE Sustain (NCT01458574), 39 patients with clinical response in OCTAVE Induction 1 were re-randomized to placebo, tofacitinib 5 mg, or 10 mg b.i.d. Efficacy endpoints included: remission (primary endpoint; total Mayo score ≤2; no individual subscore >1; rectal bleeding subscore 0); mucosal healing (Mayo endoscopic subscore ≤1); clinical response (≥30% and ≥3-point decrease from induction study baseline total Mayo score; decrease in rectal bleeding subscore ≥1 or absolute subscore ≤1). Adverse events (AEs) and clinical laboratory parameters were recorded. Results: At week 8 of OCTAVE Induction 1, 22.4% of patients achieved remission with tofacitinib (placebo, 7.7%). At week 52 of OCTAVE Sustain, 31.3% and 66.7% of patients receiving tofacitinib 5 and 10 mg b.i.d., respectively, achieved remission (placebo, 9.1%). The occurrence of AEs or serious AEs in Japanese patients was generally similar to that in the global study population, with no new or unexpected safety risks observed. Conclusions: Although patient numbers were small, tofacitinib demonstrated numerically greater efficacy versus placebo among Japanese patients in OCTAVE Induction 1 and OCTAVE Sustain, with a safety profile consistent with that of the global study population. %I Karger Publishers
